Technical Data

Electric Field Imaging Device

The MC33794 is intended for applications where noncontact sensing of

objects is desired. When connected to external electrodes, an electric field is

created.,The MC33794 is intended for use in detecting objects in this electric

field. The IC generates a low-frequency sine wave. The frequency is adjustable

by using an external resistor and is optimized for 120 kHz. The sine wave has

very low harmonic content to reduce harmonic interference.

MC33794

The MC33794 also contains support circuits for a microcontroller unit (MCU)

to allow the construction of a two-chip E-field system.
